DS1330YP-70+ General Description

The DS1330 256k Nonvolatile (NV) SRAMs are 262,144-bit, fully static, NV SRAMs organized as 32,768 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors V_CC for an out-of-tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption. Additionally, the DS1330 devices have dedicated circuitry for monitoring the status of V_CC and the status of the internal lithium battery. DS1330 devices in the PowerCap module package are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete NV SRAM module. The devices can be used in place of 32k x 8 SRAM, EEPROM, or Flash components.

Key Features

10 years minimum data retention in the absence of external power
Data is automatically protected during power loss
Power supply monitor resets processor when V_CC power loss occurs and holds processor in reset during V_CC ramp-up
Battery monitor checks remaining capacity daily
Read and write access times of 100ns
Unlimited write cycle endurance
Typical standby current 50µA
Upgrade for 32k x 8 SRAM, EEPROM or Flash
Lithium battery is electrically disconnected to retain freshness until power is applied for the first time
Full ±10% V_CC operating range (DS1330Y) or optional ±5% V_CC operating range (DS1330AB)
Optional industrial temperature range of -40°C to +85°C, designated IND
PowerCap Module (PCM) package
- Directly surface-mountable module
- Replaceable snap-on PowerCap provides lithium backup battery
